bb-rep.sh & bb-snapshot.sh

Hi all - I'm running into a problem creating the availability report and the snapshot on 4.3.0-beta2. Every time I run either command I get an "Internal Server Error". The apache logs show "Premature end of script headers" and the syslog shows that a buffer overflow was detected. The system its on is a Ubuntu 9.04 64b server. I have gone through the archives and based on what i did find i double-checked permissions(all were good).. Any ideas? The other option I have is to try to recreate the report manually.. Any ideas what datasets go into the report? thanks! -- --==[ Bob Gordon ]==--

Clientupdate problems
by rdeal＠jcvi.org 11 May '10

11 May '10

Does anyone have clientupdate working reliably for a large number of machines? I noticed a problem with clientupdate failing on our 4.2.0 server and tracked it down that once a few clients seem to request the update the server stops sending the file. The clients however happily update the clientversion.cfg and thus never attempt to get the file again. After upgrading to 4.2.3, the problem is the same. Anyone else see this? I have read some of the back forum messages and it sounds line several others have run up against this same problem but there doesn't seem to be a solution. Butch

Hi I have used a mysql script from xymonton to collect data into xymon, i get the data in xymon OK but the problem is the graphs right now. The graphs come up in the page but is not plotting, the problem is some where between hobbitserver.cfg and hobbitgraph.cfg I am asking for help while i carry on looking for the answer (maybe i'm missing something in the configuration) please note that the rrd file is created in the data folder I get the data in xymon example: Fri Mar 26 14:54:26 2010 MySQL Server OK threads: 1 questions: 990691 slow queries: 0 opens: 7128 flush tables: 1 open tables: 64 queries per second avg: 0.402 maxcon: 100 Server version: 5.0.77 Source distribution Uptime: 28 days 12 hours 19 min 1 sec Server reports timestamp of 2010-03-26 14:54:26 and have added the following in hobbitserver.cfg in TEST2RRD i added mysql=ncv and then added the following line NCV_mysql="threads:GAUGE,questions:GAUGE,slow queries:GAUGE,opens:GAUGE,flush tables:GAUGE,open tables:GAUGE,queries per second avg:GAUGE" also in hobbitgraph.cfg i added the following (i only have the first 2 instances of data for testing purposes) [mysql] TITLE mysql info YAXIS # DEF:threads=mysql.rrd:threads:AVERAGE DEF:questions=mysql.rrd:questions:AVERAGE LINE1:threads#00CCCC:threads LINE2:questions#FF0000:questions COMMENT:\n GPRINT:threads:LAST:Threads \: %5.1lf (cur) GPRINT:threads:MAX: \: %5.1lf (max) GPRINT:threads:MIN: \: %5.1lf (min) GPRINT:threads:AVERAGE: \: %5.1lf (avg)\n GPRINT:questions:LAST:Questions\: %5.1lf%s (cur) GPRINT:questions:MAX: \: %5.1lf%s (max) GPRINT:questions:MIN: \: %5.1lf%s (min) GPRINT:questions:AVERAGE: \: %5.1lf%s (avg)\n Regards Nelson Amaral ----- Original Message ----- From: "thorsten erdmann" <thorsten.erdmann at daimler.com> To: hobbit at hswn.dk Sent: Friday, 26 March, 2010 11:27:32 AM Subject: [hobbit] message filter and the DEFAULT section Hi I want to filter some messages from a specific server's message log. So I built a special rule in hobbit-clients.cfg to filter that message, but it is ignored. It seems Hobbit preferres the DEFAULT section. If I uncomment the DEFAULT LOG rule my special rule is used and the message is filtered. So how can I have a default rule including some IGNORE clauses which is used for all my servers and an additional set of rule specific to one or more servers. Here is my hobbit-client.cfg. The rule I currently playing with is marked with (***), it's the host s068c326. If I comment out the last two lines it works, if not the message "ntpd error" is detected as error.

bad time stamp causing history problems
by gus.ferrer＠mail.cuny.edu 31 Mar '10

31 Mar '10

Hi, It looks like our hobbit server rebooted back on March 12 and due to a (non-hobbit related) configuration problem on our server, the hobbit processes seem to have started BEFORE the server time and date were adjusted at bootup. So, we have lines such as this in all our the history files for all our our hobbit clients: <snip> Fri Mar 5 06:19:31 2010 green 1267787971 623047 Fri Mar 12 11:23:38 2010 red 1268411018 -14687 Fri Mar 12 07:18:51 2010 green 1268396331 1587667 Tue Mar 30 17:19:58 2010 red 1269983998 568 <snip> The entries from March 12 are out of order, with the 11:23 entry coming before the 7:18 entry. Hobbit updated the history files, then the server time was adjusted to an earlier time and hobbit updated the history files again but with earlier timestamp. Apparently, hobbit doesn't like this sort of thing, and all our history pages are showing incorrect or missing information dating back to March 12. Is there a way to fix this problem globally on my server without my having to edit each file individually (which isn't going to happen...). Or is just dropping all the history data after March 12 the answer? Thanks, Gus

need help with DISK and NFS mounts
by camorae＠googlemail.com 31 Mar '10

31 Mar '10

Hi guys, im trying to set up some trigger values into the .../hobbit/server/etc/hobbit-clients.cfg but its not working. I have a server with some NFS mounts and i had to change the .../hobbit/client/bin/hobbitclient-linux.sh to monitor them: [df] df -P -x none -x tmpfs -x shmfs -x unknown -x iso9660 with this change i can see the NFS mounts in the "disk" column. Now the problem is, that if i put some values for Yellow and Red status on the hobbit-clients.cfg or even client-side config, it does not trigger the values. HOST=nsftest DISK /nfsmount/test1 98 99 ---> this doesnt work. DEFAULT DISK /nfsmount/test1 98 99 ---> this also doesnt work. Does someone have an idea how it could work? Many thanks, Cayo

Some Infos for the CPU-Column
by andreas.kunberger＠itv-denkendorf.de 30 Mar '10

30 Mar '10

Hello, I've just had server under heavy load and while looking for the cause I noticed something weird: If you normal use top, it shows in the third line the actual cpu usage percentage. Not so in the top output in the cpu column: here it shows the avverage cpu usage since reboot. Top behaves in this line similar to vmstat. So if you need the load percentage look in the trends column or in the client data. Greetings. Andreas --
